Subsurface mining is a process that involves the extraction of a metal or fossil fuel from the ground. It is the best and most well-known mining method. The subsurface mining process is helpful in the process of mining for gold, silver, lead, and even gems. Besides this, it is very much beneficial in the mining of coal, salt, and oil …

Subsurface mining increases the risk of skin diseases, lung cancer, and respiratory diseases. This polluted exposure level is higher in mountainy areas as mountaintop removal occurs. So, the risk of infections is more elevated in residential or rocky areas. Apart from humans, subsurface mines harm wildlife.

These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.
